To distort a method for a telecommunications system, in particular for a telephone branch exchange, with the assignment of special operating functions.

The invention relates to a method for a telecommunications system, in particular for a telephone private branch exchange, with control devices, changeable and non-changeable associated with the control devices Storage and comparison means for the optional handling of switching connections or from in connection with an allocation of functions to intended for switching processes Means controlled, operational processes, whereby after initiation of the shutdown of the switching processes controlling means by transmission of a corresponding special code and / or a special identification for corresponding evaluation means of a control device processes other than switching-related processes Operations are controllable.

25 'By DE-OS 31 30 125.8 is already a method for Execution of the functional test known, in which a memory location is assigned to a changeable memory, whose memory content can be influenced via a peripheral unit in such a way that in the case of the normally active connection the main memory on the data transmission line bundle of the telecommunications system a first piece of information and in the case of functional tests to be carried out for peripheral connection units, another, second piece of information can be stored, so that instead of the main memory a determine the process sequence of the functional test-Mt 1 Bo / 7.2.1984

the memory is operative on the data transmission trunk is switched on. The aforementioned storage and retrieval of the information initiating the functional test is carried out by one of an evaluation of an on an authorized connection, for example operating or test station, issued identification or a function test command generated at a central point command issued by the executing institution. This means that by transferring a corresponding Special code and / or a special identifier for corresponding evaluation means of a control device processes other than switching processes can be controlled.

The object of the present invention is to simplify the assembly of a telephone private branch exchange to create the possibility for a customer or also retrospectively by transferring a key figure depending on a corresponding, additional evaluation in the control device in the telecommunications system, in particular in the private branch exchange to specifically assign special operating functions.

This is achieved by the fact that after switching off the switching Process controlling means by evaluating a selected and a peripheral device transferred key figure an operational process is initiated in such a way that based on the evaluation the identifier received in the control device and corresponding to the selected code number, a first function identifier (for example, for an allocation of a secretary function) in association with one of the identifier Subscriber station in a changeable, containing the subscriber station assigned information and data storage queried every time a connection is established

rather is saved.

In this way, certain terminals can have certain operating functions be allocated. This allocation can be made both during the installation of the system and subsequently in simply from a peripheral device, for example from an attendant console. The operating function can be, for example be about the allocation of a secretary function or a managerial function.

According to a further embodiment of the invention is by Evaluation of a key figure selected after a first selected by submitting a special indicator (for example Pressing a hash key) and a second code both the identifier assigned to the selected first code in the changeable memory as well as one of the further code numbers selected and the corresponding Identifier assigned identifier in the changeable memory assigned as further information which is necessary for the operation of the relevant subscriber station is decisive.

According to a further embodiment of the invention, a secretary function and / or with the first code number at least one of the other selected key figures is assigned an executive function of a subscriber station.

According to a further embodiment of the invention, comparison switching means are used to check the in the control device are to be assessed key figures and / or identifier and in the case of a lack of uniqueness Signals to request a correction or to identify the incorrect behavior and / or to delete of the already initiated state controllable.

- Tb- VPA 84 P 116 5 DE

This allows secretary and executive functions of a subscriber station can be arbitrarily allocated from a peripheral device. In the absence of uniqueness signals can be used to request a correction or to identify the incorrect behavior and / or to delete it of the already initiated state are triggered automatically.

Below is an exemplary embodiment based on the drawings of the invention described.

In FIG. 1 shows a digital private branch exchange in which the method according to the invention can be used.
15th

In FIG. 2 shows a similar system in which the method according to the invention can also be used.

In FIG. 1 is a digital private branch exchange with three interface modules SB1 to SBx shown as an example, on which either, for example, seven Subscriber stations and an exchange VP2 or office transfers AU, AU1, a switchboard VPL2 and cross-connection lines QU1 to QUΊ or subscriber stations TxO, a switching station VPIx, trunk transfers AUx1 and interconnection line transmissions QUxn, as well as data terminals DE can also be switched on. Each of the interfaces is via a corresponding trunk group LB1 or LB2 or LBx with the speech path coupling network KN and via the common data transmission line bundle DL connected to the central control device ST. The latter connection runs via the peripheral device PE, in which possibly information that cannot be processed in the control device ST at the same time are, cached and, if necessary, implemented will. About each of the trunk groups are both the voice transmission corresponding information as other data can also be transmitted using the pulse code modulation method. The exchange of information between connected Terminals, e.g. subscriber stations and switching stations, as well as connected trunk lines, Cross-connection lines and other lines are made via the speech path coupling network KN. It should be mentioned here, that via the speech channels not only the speech information, but also other information and data can be transmitted using the pulse code modulation method. There are also additional ones over the speech path coupling network, only Apparently indicated devices such as tone generators TG, code receiver CE and others not shown Devices, for example data devices and test interfaces, can be connected.

In principle, the connection is established as follows described way. In an interface assembly,

-ρ - VPA 84 P 1 1 8 5 DE

e.g. SB1, is recognized when a subscriber lifts the receiver. This participant is over the speech path coupling network with a tone generator TG and with a Code receiver CE connected. With the dialed digits, the connection request is made via the peripheral device PE communicated to the central control device ST. The completeness of a key figure and the corresponding Authorization of the calling subscriber station or the incoming busy trunk transmission is checked.' As with the connection to the tone generator TG and the further connection setup to the point to be called is also controlled for the codeer receiver CE. if required the information of the relevant interface module, e.g. SB1, depends on commands from the central control device ST to another interface module, e.g. SBx, via the data transmission line bundle DL transmitted. If necessary, data is also sent from the one via the speech path coupling network Interface assembly passed on to the other interface assembly or via the connecting line transmissions. This enables data to be exchanged with other systems without additional connecting lines. In the illustration shown, it is assumed that the subscriber terminals already have conversion devices for the conversion of analog information into digital information and vice versa (so-called codec) assigned are. The further adjustment of functions takes place in the interface assemblies shown. For the implementation of analog signals from analog terminals or analog connecting line transmissions can the interface circuit Corresponding conversion switching means (CODEC) can also be assigned to the interface assembly.

For the transmission of the voice information and the special

-. f - VPA 84 P 1 1 6 5 OE

stigen data information over the speech path coupling network KN the transmission system PCM 30 is used. With this transmission system must be in every direction 30 code words with 8 bits each are transmitted in succession within 125 με. To these 30 code words include two more 8-bit pieces of information, one for signaling and one piece of information that alternates contains a frame code word and a message word. The 30 code words together with the mentioned, another 2x8 bit a pulse frame. The pulse frames are transmitted directly one after the other. The Rahra key words the pulse frames synchronize the sending and receiving parts of the PCM 30 transmission system.

Via the data transmission line bundle I DL leading to the central control device ST, information transmitted in a message format with variable data length and that according to a high level signaling method HDLC. The information format is variable in length from 5 to 32 bytes and usually contains Address, sequence number, test character and the actual message.

In the central control device ST are for processing the received information and several different commands for the retransmission of the corresponding commands Memory and processing devices such as comparators and other switching means are available. The single ones memories and devices belonging to the central control device ST are in the following in connection with the explanation of the method according to the invention described in more detail.

In FIG. 2 shows a private branch exchange which is intended to be operable with analog signals.

This analog telephone private branch exchange is a centrally controlled system in which the central control ^{device ST 1 is assigned} a path search device (not shown) and switching means for controlling the crosspoints to be switched through, which operate in a known manner. The couplers in the system connect the speech paths through a single core. The crosspoints themselves are so-called electronic crosspoints, for example CMOS modules. In the case of the FIG. The system shown in FIG. 2 are subscriber stations T1 to Tx as terminals on a first switching stage KS1 and further subscriber stations (not shown) and other terminals can be connected to further switching stages (not shown). The intermediate lines ZLAB0 to ZLAB7 are for the coupling stage KS1 and for another

Coupling stage KS2, not shown, shows the intermediate lines ZLAB '# "to ZLAB'7. The aforementioned intermediate lines lead to couplers connected in parallel, of which only two, KP1 and KP2, are shown as examples. 20th

The interconnection of the crosspoints takes place as already mentioned with the help of the central control device ST 'and that of the central control device ST' assigned route search device .. Intercom stations different Groups are created by activating a coupling point of a coupler, e.g. KS1, the one Group and a coupling point of the coupler of the other group, e.g. KS2 for a voice connection, via which other data can also be transmitted, connected to one another. A connection of the subscriber station Tx with an exchange transfer, e.g. AU12, to establish a connection via the AL12 exchange line for example by actuating the coupling point KS1 / 1 of the coupler KS1 and the coupling point KA12 / 1 of the coupler KA12. The connection then runs via the intermediate line

- * - VPA 84 P 1 1 6 5 DE

gen ZLAB7 and ZLC71. For establishing internal connections Any crosspoints in the row or in the column can be used for the connection Inputs and outputs to the calling or the called Position are operated. In the case of the exchange coupler, on the other hand, an exchange transmission is permanently assigned to each output, via one of the inputs, i.e. via one of the intermediate lines can be assigned for outgoing connections and vice versa for incoming connections. 10

For establishing a connection within the private branch exchange and the connection is also used for the further transmission of dialing numbers to the public office a code receiver, e.g. CEx, on the line leading to the subscriber to be called is required. Also is the connection of dialing codes to the calling or called subscriber station is necessary. To this end are corresponding couplers KC11 and KT in the intermediate lines that lead to the end stations (subscriber stations, exchange) and trunk transmissions, Conduct transfers of office, inserted. The code receiver CEx is, for example, via the coupler KC11 with one of the Terminals and via the coupler KC22 with one of the trunk transmissions or cross-connecting line transmissions tied together. The code receiver is switched on, for example, after lifting the receiver at a subscriber station as a function of corresponding control commands from the central control device ST '. Selects a participant's place an exchange code, the calling subscriber station, e.g. Tx, is connected through Actuation of a corresponding crosspoint KS1 / 1 of the coupler KS1 assigned to the subscriber station for transferring the office, for example via the crosspoint KA12 / 1 of the external coupler KA12. For the inclusion of the dialing numbers to be received via the exchange transmission

ger is used, for example, instead of via the coupler KC11 now this code receiver CEx to the corresponding one occupied by the exchange transmission via the coupler KC22 Intermediate line ZLC71 switched on. There is only one coupling point in the KA12 coupler for switching through can be switched through for each line at the same time.

The connection of the audio signals, ie the audio tones, takes place partly via one of the couplers KP1 to KP2 and partly via the coupler KCE, which is inserted in the intermediate lines via which the code receivers are switched on. The tones associated with the selection are switched on via the coupler KCE, i.e. during the switch-on time of the code receiver. For example, a special dialing tone is switched on via the SWT line, the internal dialing tone via the IWT line, the exchange dialing tone via the AWT line and a continuous tone via the DTA3 line. The rhythm of the tones is determined by opening and closing the coupling points KT1 to 4 of the coupler KT. ^{The central control device ST 1} controls the clock rate via the crosspoints KT1 to 4 of the coupler KT, which are supplied with a continuous tone for the first-mentioned three dial tone types. The coupler KCE for connecting the dial tones simplifies the connection process and reduces the number of necessary crosspoints in the couplers KP1, KP2. Other tones are switched on via the couplers KP1, ΚΡ2, for example the busy tone via wire B and the intrusion tone via wire A. Potentials for the through-connection of the crosspoints are switched on via the intermediate line DSP. An audible signal can be switched on via the connection HTE in order to check the connected terminal or the connected transmission, for example by mirroring the signals. Via the intermediate lines vfO and vf1, switching stations VFO and VF1 ■ are on the connecting paths to the terminals and line

-TQ- VPA 84 P 1 1 6 5 DE

Transfers can be switched on. These operator stations can Dialing tones can be supplied directly via the coupler KT.

The code transmitter CS transmits via the appropriate coupler KA12, QS12 multi-frequency code characters as dialing codes to connected connection lines, i.e. trunk lines or cross-connection lines and that takes place this transmission depending on the ready-to-dial indicator transmitted via the respective connection line, i.e. the transmitted dialing character from the remote system. Monitoring the receipt of such The audio signal as readiness to vote is carried out via the HTE wire through the central controller.

Another coupler KS is a people search device with the terminals via the corresponding Crosspoints can be switched on. There is also an additional MOH device for connecting special audio signals, for example also provided by music during a waiting state. Establishing conference connections is possible via the coupler KK and corresponding conference sets KON0.

It can be seen from the above that the columns of the additional couplers are switched in the intermediate lines are. The lines of this coupler are either directly connected to the additional facilities mentioned or via further ones additional couplers connected directly to other facilities, e.g. operator stations and code receivers, however, additional information can be switched on via the additional coupler, for example in rhythm Tones or other information, including music, can be switched on while waiting.

The memory assigned to the central control ^{device ST 1}

rather and additional devices are described below at the Description of the method according to the invention explained in more detail.

The control devices ST according to FIG. 1, ST ¹ according to FIG. 2 contain, as already mentioned above, several different memories which serve as changeable and non-changeable memories for the handling of switching-oriented connections and also for the handling of other processes than switching-oriented processes. The respective status information for processing in the central control device ST or ST ^{1 is} temporarily stored in the changeable memories in a known manner. The information that determines the process sequence in the system is stored in the non-changeable memories. They are specific to the respective system. The data memory in which the changeable customer data information and the changeable information that determine the services and special functions of the private branch exchange are stored is referred to as DS or DS '. The information resulting from a safety test can also be temporarily stored in these changeable data memories. Such an intermediate storage may be necessary in order to carry out an evaluation when an error is detected in such a way that different error identifications are only initiated in the case of test processes which correspond to the type of error or types of error of the different error identifications in a final safety-related test sequence. Such changeable information that characterizes the allocation of functions to a subscriber station is also stored in the aforementioned data memory DS. For example, a first function identifier which is assigned to an identifier of a corresponding subscriber station in this memory DS

- 1 * - VPA 84 P 1 1 6 5 DE

is available, determine the allocation of a secretary function. Another subscriber station can through assignment the executive function can be assigned to the corresponding IDs .

The central control device ST and ST ¹ are also assigned comparison switching means V and V, which compare the incoming information with existing information assigned to certain switching states or certain subscriber stations and accordingly influence the issuing of control commands. Additional switching means SA or SA ¹ are used to introduce additional functional sequences into the telephone exchange at a later date. The central control device ST and ST 'are also assigned switching means VT and BT or VT' and BT ¹ , which relate to the switching-related or operational processes. The switching processes relate to the establishment and release of switching-oriented speech connections and connections for data transmission, while the operational processes relate to processes that serve to use the private branch exchange before switching on or after switching on in a certain way with regard to the process sequence or to set up or change the services and additional functions. These include, for example, the allocation of authorizations, the setting up of special functions and services, such as intrusion, hunt group, conference participants, secretary / boss function and also the allocation of key figures to be selected for certain functional processes. In addition, switching means SiP and SiP ¹ are assigned to the control ^{device ST or ST 1} for initiating and performing a safety check. For the reception and evaluation of control commands from an operator station or a switching station, the control

- y> - VPA 84 P 1 1 6 5 DE

device ST or ST 'also assigned special switching means BT or BT ¹ .

In the present case it is assumed that the transmission a special identification number and / or a special identifier from a switching station or from an operator station, which corresponds to the one shown in FIG. 1 and in FIG.

The examples described can be connected to the transmission path in the system or which can be transmitted from a peripheral device PG or PG 'to evaluation means of the control device ST or ST ¹ to initiate processes other than switching processes.

The processes other than switching processes are operational processes that are carried out before the system is put into operation at the customer or also afterwards to customer-specific Enter data in the system or change it afterwards. Operational processes are also used Execution of certain test procedures carried out. Corresponding the manner described in the German Offenlegungsschrift DE-OS 31 30 125.8 takes place with the Transmission of the special code and / or the special identifier a switchover from the switching technology Processes on the other processes, for example, in such a way that information is provided at a central point can be stored in order to ensure that the process sequence to be processed is either for switching Processes or other than switching processes can be controlled.

In the present case it is also assumed that the central control device ST or ST 'special means VT or VT 'are assigned, which the aforementioned special code and / or special identifier, which on the part of Switching station, the switching station, the operating station VPl or VFO or PG or PG 'sent was evaluated, so that a switchover from the switching technology possible processes to operational

technically possible processes takes place. For this purpose, a corresponding identifier is recorded in the control device ST or ST ¹ (FIG. 1 or FIG. 2), for example in a memory of the mentioned means VT or VT ¹ , and queried when each switching or operational process is initiated.

After switching off the switching processes controlling means VT or VT ¹ (Fig. 1 or Fig. 2), by evaluating the code transmitted from a switching station VPl or an operator station VFO or a peripheral device PG or PG ¹ , it is ensured that subsequent processes are processed as operational processes. For this purpose, based on the evaluation of the ^{identifier corresponding to the selected code received in the control device ST or ST 1} , a first function identifier, for example for the allocation of a secretary function, is assigned to a subscriber station corresponding to the identifier, for example

T1 in FIG. 1 and FIG. 2, respectively, into a variable containing information assigned to the subscriber station T1 and data memory queried each time a connection is established DS saved.

If with an identifier corresponding to the first selected code number in this way a special function identifier is assigned to a subscriber station can by submitting a further special Indicator, for example by pressing a hash key on every telephone, and / or a choice of a second code and the identifier assigned to the selected first code changeable memory available as well as that of a further, the respectively selected further Key figure corresponding identifier assigned memory space in the changeable memory a further in-

- y> - VPa 84 P 1 1 6 5 DE

assigned to the information that is relevant both for the operation of the first-mentioned subscriber station, for example T1, and for the operation of the further subscriber station in question, for example T2 or T3r.

In this way, for example, by choosing a first code, a secretary function of a first Subscriber station and by dialing a second code number of a second subscriber station, e.g. T2, a Executive function and a third subscriber position as a second subscriber position by choosing a third code number, e.g. T3 / can be determined with executive function.

These functions are also canceled if the identifier for the introduction of operational engineering is available Processes by choosing certain key figures.

Comparison switching means V checks the key figures and / or identifier to be assessed in the control device ST or ST ¹ (FIG. 1 or FIG. 2) in order, in this way, in the event of a lack of uniqueness, for signals to request a correction or for identification to control the malfunction and / or to delete the already initiated state.

It is possible in the manner described above in a telephone system before switching on or also afterwards functions that affect anteroom systems, to enter. If the entry made is not clear, this is indicated by appropriate signals made so that a correction is also possible.

In this way, certain terminals can have certain operating functions be allocated. This allocation is carried out by a peripheral device or by a switching

control station or an operator station. e
